Spektrum AR7300BX 7-Channel DSMX Switchsafe FBL Control System

This is the Spektrum AR7300BX 7-Channel DSMX Switchsafe FBL Control System. The AR7300BX gives you the security of a 7-channel, DSMX receiver with the precision of a BeastX flybarless system in a single unit. Itís simple to use too. No special programming interface is needed for setup and adjustment. All you need is the DSM2 or DSMX transmitter it's bound to.

Complementing this incredible technology is an integrated power bus that eliminates the need for BEC regulators. It can also handle the demanding current loads of high-voltage servos. Itís this robust power delivery system that makes the AR7300BX a great choice for big 550- to 800-size electric helis or .50- to .90-size gas/nitro machines.

Included with the system is a specially designed switch harness. Should the switch fail, it has been designed to fail in the 'on' position. A USB programmer for making firmware updates (SPMA3030) is available separately.

Bought one of these for my E7. The unit is a bit larger then the AR7200 which may make it tough to use on smaller heli's. the switch and the power lead is a huge plus for me since I always use a external 2s RX pack. You will have to use HV servo's with this unit since there is no voltage regulator. IMO, the price drop makes this a no brainer...
